Why it works: Pineapple and sugar are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 4,841 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

What each ingredient does
- Pineapple
- Provides the fruit base, juice and pulp that form the marmalade's body and flavor.
- Granulated sugar
- Draws water out of the fruit and, when boiled, thickens the mixture while adding sweetness.
The step that matters
Boiling until clear. Boiling concentrates the sugar and pineapple until the mixture thickens and sets. Stopping too early leaves it runny and prone to spoiling, while boiling too long can darken it and give a caramelized, bitter flavor.
